Macaulay’s method and poisson’s ratio : document transcript
This is a document transcript for Macaulay’s Method & Poisson’s Ratio (Edexcel HN unit – Mechanical Principles (NQF L4)). It examines a method of analysing the bending moment and shear force distribution along a uniformly loaded, simply supported beam. The method used is Macaulay’s and the stages involved in this method are described in detail. The method also determines the position of the maximum bending moment, the slope and deflection at this point. Poisson’s ratio is the ratio bet

Historical skills : dating documents
Explains the different dating conventions employed in historical documents. For example, the system of dating by reference to a religious feast day and the year of the reigning monarch has little in common with the modern calendar. Even where a recognisable date is provided, it may not be what it at first appears.... The resource includes a glossary, bibliography and translation of relevant Latin numbers/phrases. Illustrative images of items from our collections appear throughout.

Fe, C 0.07, Mn 2.3 (wt%) steel, carburised at 950°C
After initial casting of this steel it was subject to a process known as carburisation. The metal is heated to above the ferrite-austenite transition in a carbon atmosphere. This establishes a concentration gradient and hence carbon diffuses into the steel. Usually the steel is then hardened by quenching. This produces what is known as a case hardened steel - with a hard surface (case) surrounding a tough core. The carbon gradient can be seen in the changing shade of the sample from left to righ

Strain-induced birefringence in a notched polycarbonate bar
The colours in the image are the result of birefringence and relate to the strain-induced alignment of the polycarbonate molecules. Because the specimen is below the glass transition temperature of PC (145 °C), the material will relax when the stress is removed and there will be no residual alignment. The colours reveal the pattern of stress concentration around the notch.
